The new STi's are pretty quick but they're actually heavier and a little slower than the older ones. I believe the 06-07's were the quickest stock and quickly went downhill from there lol (stock anyways)
The new ones look pretty slick. They have bigger intercoolers, turbos, non-restrictive exhausts now and usually a Cobb Stage 2 puts them into the mid 12's with pretty much basic mods. Their gearing is designed rally inspired though (short lower gears 1-3 and broader mid-top gears) so it's usually easy to outrun them from a 50 roll unless they have a lot of power. Kind of a weak spot, funky power band or them. Too high for 2nd and the lower end of 3rd, totally kills it for them lol
I think it'll be pretty close from a roll if he pure stock....
